Flash memory for additional non-volatile storage on Teensy 4.1 and Audio Adapters
DESCRIPTION
The Teensy 4.1 and Teensy Audio Adapter boards supports 1 of these 8-pin 16MB NOR Flash chips to expand the memory on the module to 16MB (128M-bit).
PACKAGE INCLUDES:
- Winbond W25Q128JVSIQ SMD IC
KEY FEATURES OF 16MB SERIAL FLASH:
- 16MB (128 M-bit) memory organized as 65536 pages x 256 bytes
- SPI/QSPI Interface
- 133MHz clock rate
These ICs provide additional non-volatile memory for the Teensy 4.1 board as well as the Teensy 3.x and Teensy 4.x Audio Adapter boards. They are typically used to store sensor data, sound files, image files or similar types of data. Although the external Flash can’t be used for to increase the space for programs, in some cases it may help to extend program memory space by providing a way to store large data structures that can be read into the program as needed.
The larger footprint supports one of these 16MB Flash chips. In addition 8MB volatile PSRAM memory can be installed on the smaller footprint as shown in the pic.
The PaulStoffregen/LittleFS Library can be used to work with this chip.
When used with the LittleFS file system, the 16MB/128M-bit Flash chip uses the LittleFS_QSPIFlash constructor.
